[Java] Multi-batch dictionary bug in ArrowFile{Reader|Writer}

[manolama]

Describe the bug, including details regarding any error messages, version, and platform.

Arrow 13:

I ran into an issue with the Java ArrowFileWriter where only the first dictionary batch is flushed to the file and subsequent batches are skipped. Similarly, on reading, only the first dictionary block is read and used for subsequent data blocks, resulting in out of bounds exceptions or incorrect data. It seems as if the intent was to encode with delta encoding per https://arrow.apache.org/docs/format/Columnar.html#dictionary-messages but the isDelta flag is false on writes and I wasn't able to find an API to adjust that setting.

Re. the PR, looks like we need a format schema change first. closing this issue.
